PBT assessment: overall result

PBT status:
the substance is not PBT / vPvB

Persistence: Standard degradation experiments showed that 2-EHN could not be considered readily biodegradable. The poor biodegradability of 2-EHN might be the consequence of two factors, first the low occurrence of micro-organisms able to use it as carbon source, and second its inhibitory effect on bacterial growth even at low concentration. It is assessed as 'P'.

Bioaccumulation: No experimental data on bioaccumulation are available. Based on the log Kow and the QSAR estimate of BCF, it can be expected that the substance is not bioaccumulative.

Toxicity: The substance is clearly not toxic as demonstrated under 8.1.3. Consequently, according to Annex XIII criteria, the substance is not PBT. Summary: 2-Ethylhexyl nitrate does not meet the B criteria based on screening data and also, it considered not to meet the T criteria. It may meet the P/vP criteria according to screening data.

It is concluded that the substance is not considered as a PBT/vPvB substance.
